IT SECURITY Network Security |

Network security has historically been approached as a collection of products used primarily to secure the network perimeter or site-to-site connectivity. Today, finding and fixing individual network security holes and point problems are not enough because the cost of security breaches or disruptions is high and can take many forms. These include network downtime, theft of proprietary information, loss of revenue, diminished goodwill, the cost of diverting staff from critical projects to respond to breaches, and reduced IT and business productivity. The availability of sophisticated exploits, the proliferation of software vulnerabilities, and the growing level of terrorist and criminal activity directed at communications networks have heightened the need for network and system security. In addition, networks carry more mission-critical applications than in the past, making the costs of downtime severe and the need to minimize security breaches and downtime crucial.
Security now requires a system-level approach to securing the entire network—the perimeter, data centers, campus LAN, wireless LAN, desktops, and endpoint hosts. Securing the network is an ongoing process that enables the corporation to help ensure the efficient and effective pursuit of corporate missions and goals. Every organization needs a comprehensive network security process that aligns business goals with network capabilities and technical requirements. An effective approach to network security prevents the loss of customer or partner data. It controls resources, complies with regulations, and helps avoid or mitigate potential legal and financial liabilities. It employs designs, processes, and systems that help protect critical resources and facilitate user access.
A properly designed and applied security process should be aligned within the framework of a company´s corporate governance, IT governance, and network governance systems. A well-designed network governance model optimizes stakeholder value, recognizing the needs not only of shareholders, but also of customers, suppliers, employees, and other stakeholder communities. A security process that is firmly embedded in and built around network governance will have elements of network security policy, goals, assessment, implementation, and operation.
